Matt, I have four MB's and do all my own repairs except aoto tranny rebuilds and may tackle that. Some parts on a mercedes are expensive ,I just paid 134 for a coil not quiet like a coil for a small block Chevy. But if Mercedes's get in your blood with their their handling,style, comfort, saftey and that hard to define quality found in very few other makes then that is what we are paying for.If speed for the money were my objective I'd buy a WRX..........

Going to have to guess that overall BMW's will be more expensive to repair and maintain than MB's. Of course doing ones own repairs is a big part of the pleasure of owning a quartet of them for me.............
